Summary
samba vulnerability
Details

USN-3353-1 fixed a vulnerability in Heimdal. This update provides the corresponding update for Samba.

Jeffrey Altman, Viktor Dukhovni, and Nicolas Williams discovered that Samba clients incorrectly trusted unauthenticated portions of Kerberos tickets. A remote attacker could use this to impersonate trusted network servers or perform other attacks.
